WILLIAM GUTENKUN ST, OF MIIJVAUKEE, W'ISCONSIN.

FODDER-SHREDDER.

SPECIFICATION, forming part of Letters Patent No, 578,234, dated March2, 1897,

Application filed 6 29, 1896' Y To all whom it may concern:

Be it known that 1, WILLIAM GUTENKUNs'r, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented new and useful Improvements inFodder-Shredders, of which v the following is a specification.

My invention relates to improvements in that class of fodder-shreddersin which the teeth are removably secured to a series of holding disks orplates secured on a rotary shaft.

In a former application, Serial No. 567,700, filed November 2, 1895, Ihave described a shredding device constructed on such a plan, and mypresent invention maybe considered as an improvement upon theconstruction therein described.

My present invention relates particularly to the construction of thetooth-holding disks whereby the spirallyarranged shredding teeth areheld in a position to revolve in contiguous parallel planes, there beingno spaces between the planes of rotation of the successive teeth, andthe disks being formed to interlock with and reinforce each otherthroughout the series.

The object of my invention is to provide a form of casting of sufficientstrength to withstand the strain imposed upon it and at the same timesecure the maximum efficiency of the shredder by holding theshredding-teeth in a position with their planes of rotation injuxtaposition.

In the following description reference is had to the accompanyingdrawings, in which Figure 1 is a side view of my improved shredder, andFig. 2 is a side view of one of the shredding-disks.

Like parts are identified by the same reference letters and numerals inboth views.

Each of the disks A is adapted to retain four shredding-teeth, of whichtwo are located on each side, the teeth being for convenience designatedas numbers 1, 2, 3, and 4.

Referring to the drawings, it will be observed that the teeth numbered 1and 2 are located in recesses upon one side of the disk and thosenumbered 3 and 4 are upon the other side; but while the recesses of theteeth 1 and 4 are of the same depth as the thickness of the teeth thoseof the teeth 2 and 3 are twice that depth, and as the disk is in thick-Serial No. 597,338. (No model.)

ness equal to four times that of one tooth it is obvious that the planesof rotation of all the teeth are thus brought serially into juxtaposition with each other and with the teeth of the adjacent disks.

The teeth are provided with a rearward eX- tension 13, and the recessesare made to conform in shape to the teeth, with a lug or pin 0projecting upward from the base of the recess through a hole in thecentral portion of the tooth, as described in my former application.Each of the disks is also provided with a raised or thickened portion D,which projeots into the deeper recess of the adjacent teeth and not onlyholds the tooth in place in such recess, but also serves to interlockthe disks together.

The above described construction is of great importance in enabling meto locate the teeth in the requisite proximity without weakening thecasting, and also in the provision made for interlocking the diskswhereby each of the disks in the series is made to reinforce thoseadjacent to it.

In other respects the construction herein shown is similar to thatdescribed in my former application, the disks being so secured to theshaft as to cause the teeth to assumea spiral arrangement upon the shaftand the end disks being screwed upon the shaft to the right and left,respectively, or toward the center, so as to bind the intermediate disksbetween them.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a fodder-shredder, a series of toothholding disks each formed withteeth-retaining recesses of unequal depths in each side, whereby theteeth are held in a position with their planes of rotation in juxtaposition; said disks being also provided with projections D adaptedto interlock in the deeper recesses of the adjacent plates, whereby theteeth of the respective disks are held in place and the disks are madeto support each other against the annular strain, substantially asdescribed.

In testimony whereof I affix my signature in the presence of twowitnesses.
